Hello,
i try to use iptables ... -m set --match-set against ipset infrastructure
(using night build 20151116, kernel 4.2.3)

I have some suggestions after i successfully make it works. And thanks 
you - my router is more powerful.

1) In manpage file in libxt_set.man:
Until i experience and look into code I do not understood what is mean 
by  "test src,dst"

Please add some more example to this man page to make it better:

If you have ipset table MYIPS hash:ip type and want matching by source 
ip use
iptables -I FORWARD -m set --match-set MYIPS src -j LOG
if you have ipset table MYIPS bitmap:ip,mac type and want match by 
source ip and source mac use
iptables -I FORWARD -m set --match-set MYIPS src,src -j LOG
or add any other

2) name of option "--match-set"  is not in logic used by iptables,
i suggest to change to "--set-match"

Look for other options in iptables-extensions
-m hashlimit --hashlimit-above
-m limit --limit-burst

Also name in -j SET could be reversed (--set-map)

3) Could have target -j SET  have some options to jump to some iptables 
chain by some value stored in ipset.
For example if you stored  skbmark with ip address you can change in one 
rule mark of packet matched in list

iptables -j SET --map-set MYIPS src --map-mark

but if you have chain for example customer_0000 customer_0001 ... 
customer_ffff
you have no way how to jump in one rule, and you have to need some 
hiearchicaly chains mainly generated by script.

Something like "JUMP" using mark or using some value stored with ip with 
skbmark

iptables -j SET --map-set MYIPS --map-jump-mark-prefix "customer_"
so when you match in ip in ipset table, find mark and then make jump to 
specific chain.

4) Do you have any plan when you release stable iptables 1.6.0 :-) ?

Best Regards
